In connection with the development of the hydrochemical method of prospecting for gold and other minerals, attention has now increased to the study of microcomponents in ground and surface waters of the Aldan district. The general plateau‑like character of the relief of the Aldan district in some areas is broken by the presence of solitary golets ridges and ridges, where the rivers of the district originate. The hydrographic network belongs to the basin of the Aldan River and its major tributaries – Timpton, Yakokit, Selligdar. The climate of the district is sharply continental with annual precipitation of about 440 mm and an average annual negative air temperature of -6 °C.
